Understanding mechanical systems such as printers, car sunroof systems or aircraft landing gear can be challenging. Many CAD-based tools offer a kinematic solution that helps designers avoid problems during a particular movement. However, a kinematic analysis in itself does not provide all the information you need, such as the dynamic loads that occur during a movement and how much force an actuator should be able to generate. Simcenter™ 3D Motion Simulation does provide this.
The advantages of Motion Simulation
- Gain insight into the kinematic and dynamic behavior of assemblies and mechanisms
- Find dynamic forces in connections and reuse them in a structural analysis
- Validate a mechatronic system by means of a link with controller software
Co-simulation with operating systems
Today’s products often have different controllers that include electronics, hydraulics, and software components. The behavior of the operating system affects the hardware mechanical system and vice versa. Therefore, it is of great importance for engineers to understand these effects while developing their systems. Simcenter™ 3D allows you to combine mechanical designs with operating systems to verify that the operating system design is robust enough to control the dynamic mechanism and help prevent costly changes later in the development process.
Within motion analyzes, infinitely rigid components are usually used. This approach is acceptable for most situations, but a more accurate representation is the use of Flexible Bodies. These flexible components can deform elastically during movement due to dynamic effects and loads. This gives you a better insight into the performance of parts and mechanisms.
When designing new assemblies, consider the packaging space in which the assembly operates and whether components will not collide with the surrounding geometry. Simcenter™ 3D helps you solve this problem with its multibody dynamic solver that can calculate the displacement and position of assembly components connected to springs, bushings and flexible components. By using your geometry directly, you know if you need to make design changes to avoid problems like collisions.
The basis of multibody dynamics starts with “Rigid Body Motion” and is the fastest way to gain essential insight into the movement characteristics of your product. Simcenter™ 3D gives you the right tools for detailed motion analysis of infinitely rigid components. You make your motion model simple, directly from your CAD assembly via an automated conversion process based on existing assembly constraints. Or you build your own model from scratch. In addition, you can also easily model and simulate contact between multiple components.
